Sunglasses protect not only your eyes from the sun but also protect your eyelids and surrounding skin tissue. The sun emits massive amounts of ultraviolet (UV) radiation which causes premature skin cell death as well as damage to skin cell DNA.
Astigmatism is a common refractive error (glasses need) and is often associated with other refractive errors such as myopia, hyperopia and presbyopia. Astigmatism is not a disease process and we all have it in varying amounts.
Inside of your eye, directly by the pupil, sits a small lens about the size of a plain M&M. This lens is responsible for focusing light on the retina in the back of the eye. Any clouding of this lens is called a cataract.
Farsightedness, or hyperopia, is a common refractive error such as myopia, astigmatism, and presbyopia. As the name implies, patients with hyperopia are sighted more for far than they are for things up close.
Glaucoma is a group of eye diseases in which the optic nerve that transmits the eye’s image to the brain is under pressure greater than what is can withstand. This pressure damages the nerve causing permanent vision loss.
The Iris is the colored part of the eye and its primary function is to control the amount of light entering the eye by regulating the size of the pupil. Iritis is a condition in which our body’s immune system gets confused and attacks the iris.
